What should I do if I go to the gym for the first time and feel inexplicably nervous and shy?

Hello, I had your feelings and experiences the first time I went to the gym. I was so shy at that time that I felt afraid to go anywhere! At this time, I suggest you talk to the coach and ask him what to do as a novice when you come here for the first time. Where to start and ask his advice? Then do it step by step according to his idea!
